Specification of Letters Patent.

Patented Nov. 4, 1919.

Application filed November 24, 1917. Serial No. 203,716.

To all whom it may concern:

Be itv known that we, EDWARD W. ROBIN- soN and CHARLES .lnwnnn RoBrNsoN, citi- Zens of the United States, residing in Savannah, Georgia, have invented certain Improvements in Securing Heads in Wire- Bound Barrels, of which the following is a specification. I

Our invention is an improvement upon the method of securing heads in the ends of wire-bound barrels for which Letters Patent No. 1,197,153 were granted on the 5th day of September, 1916, the object of our pres ent invention being to effect the securere- *tention of the barrel head without the use,

upon the latter, of the external batten which constitutes an element of the head shown in said patent.

This object we attain in the manner hereinafter set forth,-reference being had to the accompanying drawings, in which Figure 1 is an end view of the barrel with the head in place therein but not secured thereto, and with a tightening band surrounding the end portion of the barrel;

Fig. 2 is a similar view with the head secured in position in the barrel and with the tightening band removed;

Fig. 8 is an end view on a reduced scale of the wire bound stave structure of the barrel, illustrating said stave structure as it appears when the parts are in the relation to each other shown in Fig. 1, and

Fig. 4 is an enlarged transverse section on the line 44, Fig. 1.

In the drawings, the wire bound staves of the barrel are represented at 1, these staves, before the insertion and securing of the head in the barrel, being, at least so far as regards their end portion, in the condition shown in Fig. 8, that is to say, being disosed in a se mental series with a a 09 be- .P e

tween the terminal staves of the series.

In order to close this gap a split hoop is applied to the end of the series of staves, this hoop having a central channel member 2 for embracing the ends of the staves and being originally in the segmental form shown in Fig. 1, with a gap w between its ends. The outer flange of this channel hoop 2 bears againstthe outer faces of the staves and has a hollow bead 3 for embracing the external binding wire of the outermost pair,

as shown in Fig. 4, and the inner flange of the hoop bears against the inner faces of the staves and has a radially projecting flange 5, as shown in Figs. 1 and 4.

The head of the barrel may consist of a s ngle piece or it may be composed of any desired number of sections disposed side by side, as represented, for instance, at 6 in Fig. 1, the periphery of the head having formed therein, preferably midway between the top and bottom of the head, a kerf 7, whose depth may be equal to or slightly in excess of the width of the flange 5, as shown in Fig. 4.

The first step in the operation of securing the head to the barrel is to engage the flange 5 of the end hoop with the kerf 7 when the parts are in the position shown in Fig. 1, the extent of engagement of the flange with the kerf being, preferably, greatest at the polnt opposite to the gap m in the hoop and gradually decreasing from that point toward the gap, at which latter point the flange may be entirely free from engagement with the kerf. A split clamping band 8 is now applied to the outside of the end hoop 2, and is gradually tightened by turning the screw stem 9 until the gap at between the terminal staves of the barrel and the gap a? between the ends of the hoop are closed, as shown in Fig. 2, the flange 5 of the end. hoop being now in full retaining engagement with the kerf 7 throughout the entire periphery of the head. The hoop 2 can then be retained in its tightened position by means of any suitable fastening device, as for instance, by means of a staple 10 engaging the meeting points of the hoop, as shown in Fig. 2, the clamping band 8 having formed therein, at a point opposite to the tightening screw 9, a slot 11 for the introduction of said staple.

After the hoop has been thus secured in its tightened position, the clamping band 8 may be removed, as shown in Fig. 2, the engagement of the flange 5 of the hoop with the kerf in the periphery of the head serving to eflectually retain the latter against either inward or outward displacement, and also serving to prevent leakage around the head if there is a proper snug flt between the flange 5 and the kerf 7.

We claim:

The mode herein described of securing a head in the end of a wire bound barrel, said mode consisting in applying to the end of the wire bound set of staves, while the terininal staves of the set are separated from one another, a split hoop having a flange projecting radially inward therefrom, said hoop likewise having separated ends, placing within said split hoop a complete head having a peripheral keri' therein, engaging with said kerf that portion of the flange of the hoop opposite the split ends thereof, surrounding the hoop by a split clamping ring which contacts throughout its extent with the exterior of the hoop, then causing the ends of said split clamping ring to approach one another, thereby bringing together the terminal stav'es of the set and the ends of the split hoop and causing the flange of the hoop to enter the peripheral kerf of the head throughout the circumference of said head, and then, while the hoop is still confined in the clamping ring, securing together the adjoining ends of the contracted hoop.

In testimony whereof, we have-signed our names to this specification.
